C#: A step into a new system, where game-specific formats can be defined as plugins, preventing users from having to download DSDecmp itself again and again. Such plugins must be stores in a 'Plugins' folder in the same location as the DSDecmp.exe.
...
To keep the base program mobile, all native NDS formats do not require plugins.
The 8-bit Huffman format cannot be used to compress at the moment; thanks to CUE a bug has been found where the offset-field of a node overflows, corrupting the compressed file.

C#: added the Golden Sun: Dark Dawn format in the new structure. This version hasn't been tested yet, and thus hasn't been included in the main program. I also need to think of how to include these game-specific formats in the main program, as they may conflict with built-in formats regarding their header (with GSDD I just try to decompress the file when checking if a file is supported).

C#: implemented Huffman compression for both 4-bit and 8-bit block sizes. It will not result in compressed files identical to those found in games, as I'm currently not in the mood to figure out exactly what heuristic they use to build the Huffman tree.

C#: made a start on the Huffman compression algorithm; the Huffman tree for 8-bit datablocks is now created.

C#: added a variation to the original LZ-10 compression algorithm that increases the compression rate, while still ensuring compatibility with the built-in decompression.

C#: removed the BitConverter reference in the Huffman decompressor, and replaced the call with one to a local utility method (to be sure that the byte*->u32 conversion always uses the correct endianness.

C#: Extended the generic Supports(Stream) method with the length of the input stream, since Overlay-LZ compresses from end to start.
